Voxel stands for which of the following?

Explanation:
In 3D medical imaging, a voxel is the smallest unit of the volume you can sample. It stands for Volume Element, just like a pixel is the smallest unit in a 2D image. Each voxel represents a tiny box in the scanned object and carries an intensity value that encodes properties like density or signal strength. By stacking many voxels in a 3D grid, we construct the full volume image. The other terms don’t fit as well: a Visual Element would suggest something about appearance rather than a sampled volume, Very Element isn’t a standard term, and a Vertex Element would refer to a corner point, not a volume sample.
